The 6-foot-6, 319-pound McQuistan returns to the Cowboys after two years away. He was a seventh-round selection 2006 out of Weber State, and he appeared in 40 games with the Cowboys, including every game in 2007 and 2008. The Cowboys traded him to Miami in 2010, and he played in eight games for the Dolphins. He spent 2011 with the New Orleans Saints, appearing in 10 games.

The Cowboys start a three-day minicamp on Tuesday. They'll meet again in training camp in Oxnard, Calif., on July 30, but the rookies and selected veterans will have three days of work the week before at Valley Ranch before leaving for camp.
